摘　　要：介绍了酮苯脱蜡装置加工残渣润滑油料时负荷受限的解决措施,指出了影响装置残渣润滑油料加工负荷的主要原因是过滤机过滤速度低,通过延长过滤机温洗时间、提高三次稀释溶剂比等措施未能有效解决过滤速度低的问题。结合残渣润滑油料中蜡结晶的特点以及残渣润滑油料工况下蜡膏形态,判断出造成过滤速度低的主要原因是蜡结晶效果差使蜡晶体细小且含油高,增加了过滤阻力。有针对性地加入预稀释溶剂改善了蜡结晶效果,解决了过滤速度低的问题,装置残渣润滑油料加工负荷提高了37%,蜡膏含油最大降幅19%,提高了装置经济效益。The measures to solve the load limitation during processing residue lubricating oil by ketobenzene dewaxing device were introduced, and it was pointed out that the main reason affecting the processing load of residue lubricating oil by the device was the low filtration speed of the filter, the measures of prolonging the warm washing time of the filter and increasing the solvent ratio of three dilution did not effectively solve the problem of low filtration speed. Combined with the characteristics of wax crystals in the residue lubricating oil and the shape of wax paste under the working condition at that time, it was judged that the main reason for the low filtration speed was the poor effect of wax crystals, which led to the tiny wax crystals and high oil content to increase filtering resistance. Specifically adding prediluted solvent improved the crystallization effect of wax and solved the problem of low filtration speed. The processing load of the residual lubricating oil material of the device was increased by 37%, and the oil content of wax paste was decreased by 19%, the economic benefits of the device were improved.
